"Salak volcano was constructed at the NE end of an eroded volcanic range. Satellitic cones occur on the SW flank and at the northern foot of the forested volcano. Two large breached craters truncate the summit of Gunung Salak. One crater is breached to the NE and the westernmost crater was the source of a debris-avalanche deposit that extends 10 km WNW of the summit. Historical eruptions from Gunung Salak have been restricted to phreatic explosions from craters in a prominent solfataric area at 1400 m on the western flank. Salak volcano has been the site of extensive geothermal exploration." -Smithsonian Volcano Archive
